Abstract
A mount assembly for use in a vehicle includes a primary component sandwiched between a pair of secondary components. The primary component is secured to a first member of the vehicle, and the secondary components are secured to a second member of the vehicle. The primary component has a tuned performance characteristics different than the tuned performance characteristics of the secondary components. Each of the secondary components function in series with the primary component between the first and second members such that the mount assembly has multi-rate decoupled dynamic stiffness performance.
Claims20
A mount assembly comprising:
- a first vibration absorbing component secured to a first member, said first vibration absorbing component having first tuned performance characteristics;
- a second vibration absorbing component secured to a second member, said second vibration absorbing component having second tuned performance characteristics different than said first tuned performance characteristics, said second vibration absorbing component engaged in series with said first vibration absorbing component for transmitting forces between said first and second members;
- and
- a third vibration absorbing component secured to said second member, said third vibration absorbing component having third tuned performance characteristics different than said first tuned performance characteristics, said third vibration absorbing component engaged in series with said first vibration absorbing component for transmitting forces between said first and second members, said first vibration absorbing component being disposed between said second and third vibration absorbing components.
A vehicle suspension assembly comprising:
- a vehicle frame adapted to support a body of a vehicle;
- a strut rod adapted to be coupled to a vehicle suspension system;
- a first vibration absorbing mount component secured to said vehicle frame and slidably coupled to said strut rod, said first vibration absorbing mount component having a first tuned performance characteristics;
- and
- second and third vibration absorbing mount components secured to said strut rod on opposite sides of said first vibration absorbing mount component, each of said second and third vibration absorbing mount components engaged in series with said first vibration absorbing mount component for transmitting forces between said vehicle frame and said strut rod, said second and third vibration absorbing mount components having second and third tuned performance characteristics, respectively, said first tuned performance characteristics being different than said second and third tuned performance characteristics.
A method of mounting a vehicle suspension system, the method comprising:
- securing a primary vibration absorbing mount component to a vehicle frame;
- movably coupling said primary vibration absorbing mount component to a member of the vehicle suspension system;
- and
- positioning a pair of secondary vibration absorbing mount components on said member at opposing sides of said primary vibration absorbing mount component so that each of said secondary vibration absorbing mount components are engaged in series with said primary vibration absorbing mount component for transmitting forces between said vehicle frame and said member, said primary vibration absorbing mount component having a different tuned performance characteristics than said secondary vibration absorbing mount components.
